APPARATUS FOR BANDING BOXES 3 Sheets-Sheet 5 Filed June 25, 1954 VIA 1 Patented July 23, 1935 UNITED (STATES v attest? APPARATUS FOR BANDING BOXES Bror Anders Emil JohnsoniAlsten,Sweden, as-

signor to Aktiebolaget Gerh. Arehns, Mekaniska Verkstad, Stockholm, Sweden, a corporation of Sweden Application June 25, 1934, Serial -No.-73 2,319 In Sweden July 1, 1933 I T 9 Claims. (01. zit-+53) This invention relates to an improved apparatus for applying pasted strips, labels or the like to boxes, packings or the like for instance match boxes or cigarette packings.

v One object of my invention is to safely secure such strips etc. to boxes etc. even though the strip is not completely pasted.

Another object of my invention is toprovide a particularly smooth attachment of the strip to an underlying surface.

Still another object of my invention is to obtain a safe attachment of the strip to an underlying surface and nevertheless save a considerable amount of paste.

Thus it is also the object of this invention to remove certain inconveniences affecting certain strip-sealings. Such sealing may for instance be effected on drawing by means of a pincher a'strip from a pile in a magazine, over a pasting device and supplying it to a box to be sealed. In such case one end of the strip is seized by a pincher or the like. The strip edge covered by the pincher is incompletely or not at all pasted and if said edge is by means of a stamp pressed against a box side the paste adhering to the middle portion of a the strip will not be squeezed out to said edge which will then not adhere to said box side. Nor will a sufficiently smooth afiixing of the strip be obtained. Ac-

0 cording to the invention however the entire strip is safely secured to an underlying surface and the outer surface of the strip applied will have a very smooth surface well adapted for subsequent stamping. By this invention it is possible to spread out by squeezing the adhesive to a very thin layer. Thus a comparatively thick layer of paste may be applied to a middle portion of the strip and nevertheless the subsequent operation will effect a paste layer much thinner than can be obtained by pasting the entire surface of the strip. 7 V

With these and other objects not specifically mentioned in view, the invention consists in certain new constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the drawings:

Fig. 1 is a side view of the apparatus embodying the invention;

Fig. 2 is a front view of the apparatus; and

Figs. 3-5 illustrate various steps of a banding operation.

Referring now to the drawings the box to be sealed rests in an inclined position in a chute 2,

So that its front sideB occupies a higher position than its rear side. In front of the box side 3 there is provided a magazine 4 for strips and a pastesupply 5 having a perforatedpasting' pad '6. .Abovetthebox I a pincher 'l ismovable towards and from the pasting pad. The pincher is connected to a swinging arm 8 fulcrumed on a shaft t in the machine frame it and carries a roller l l, which is by a tension spring l2 pressed against the peripheryof a cam' l3. The cam I 3 j is secured to a continuously rotating driving shaft An arm lSactuated by a tension spring I3 is secured to a swinging shaft It in the frame I0 and supports the smoothing member's. arm I a is rigidly secured to the shaft l6 andsupports a roller l9 which is by the springIB forced against the'periphery of'a'cam 2&3 securedto Another the shaft 14." The arm l5 carries a pin 23 to which are pivoted two arms 2| and 22 respectively. The arm 2| constitutes together with an.- other arm 28 having a roller 29 a double armed lever. The roller is by means of a tension spring 39 forced against the periphery of a cam 3| which is secured to the shaft M. The arm 22 forms. together with another arm 24 having a roller 25 a double-armed lever. The roller '25 is by means of a tension, spring 28 forced against the periphery of a cam 21 which is secured to the shaft I4. The end of the arm 22 supports an adjustable finger 34 which is provided with a roller 36 jour nalled on'a link 35 on the finger 34. The link is adjustable to occupy different angular positions. The finger 34 is held by aspring 3'! in a definite angular position relative to the arm 22 whereby said spring forces an abutment'tii on said arm against a set-screw 39 in the arm 22. Thus the finger 34 may yield upwards in a direction from the box I. The arm 2! carries a link 33'which is adjustable to occupy different angular positions and provided with a roller 32.

The applying, of strips is effected by means of the apparatus described in the following manner.

7 A strip 40 from the magazine 4 is on the'pastin'g pad 6 supplied with paste only at its middle portion. Thereafter the pincher l fetches the strip seizing it at its right hand edge which has not been pasted. The strip is moved by the pincher into the position above the box I shown in Fig. 3. Thereafter the arm l5 moves the smoothing mechanism downwards, so that the roller 32 will primarily engage the strip near the upper edge of the inclined box side 3, whereafter it is lowered further until the rollers have reached the position shown in Fig. 4. Then the roller 36 will engage the strip on the upper side of the box in the proximity of the upper edge of the box. At this moment the cam 37 will permit the spring 26 to swing the arm 22 towards the box I on further descending of the arms 2| and 22 and the pincher l releases the strip. Then the roller 32 continues smoothing out an end of the strip about the box side 3.

somewhat increasing pressure press upon the strip end which is smoothed out about the upper box side, by moving the roller 36 along said side. Ob-

viously the strip is thereby straightened so that it,

will cover both box sides very smoothly and furthermore be correctly bent over the upper front edge of the box to obtain the position shown in Fig. 5. The result now referred to is obtained by moving the rollers 32 and 3% on descending the arm l5 towards said front edge in an oblique direction relative to each box side i. e. not parallelly with anyone of them. Owing to the fact that the roller 32 will hit the strip on the box side 3 in an oblique direction close by said front edge, the part of the strip that covers the box side close by said edge will be safely applied and adhere .to the front box side even though said side would be bulged inwards, which latter will often occur. This improved effect will of course also be obtained at the upper box side.

The scope of my invention should not be limited to the precise details thereof now described and illustrated in the drawings. Thus any member for the same purpose may be substituted for the smoothing rollers. The strip etc. may be applied to a single surface or to any number of surfaces of a box etc. The strip etc. may be supplied to the box etc. in any way. However the transferring of the strip to the box in the manner above described is particularly convenient for subsequent applying of the strip according to my invention.
